20110181130 | COOLANT-COOLED LINEAR MOTOR - In a coolant-cooled linear motor includes an armature including armature windings and a cooling jacket arranged to surround the armature windings, the cooling jacket unit includes four cooling jackets defining four side faces parallel to the extension direction of the armature and two end blocks defining two opposite end faces in the extension direction of the armature, the cooling jackets and the end blocks being connected to one another in a box shape. Each of the cooling jackets has an internal space to be supplied with a coolant; and a field magnet unit includes a yoke made of a ferromagnetic material and permanent magnets arranged in the yoke, one of the armature and the field magnet unit making relative movement with respect to the other. | 07-28-2011 |
20130009505 | ROTARY ELECTRIC MACHINE - A rotary electric machine includes a stator; and a rotor including an iron core, which has a tubular connecting portion surrounding a shaft and 10 magnetic pole portions integrally formed with the connecting portion corresponding to a pole number, and a plurality of permanent magnets arranged between the magnetic pole portions. The iron core includes axially-penetrated magnet accommodating air gaps formed between the magnetic pole portions at the radial outer side of the connecting portion, and the permanent magnets are installed in the respective magnet accommodating air gaps such that a radial outer surface of each of the permanent magnets makes close contact with an inner surface of each of the magnet accommodating air gaps and such that a gap exists between a radial inner surface of each of the permanent magnets and the connecting portion. | 01-10-2013 |
20140035419 | ROTOR, ROTATING ELECTRICAL MACHINE, AND MANUFACTURING METHOD OF THE ROTOR - The rotor includes a rotor core in which the pore is shaped in the center and the magnet is arranged on the circumference of the pore, and a shaft, in which, by means of a knurling tool being partially shaped on the peripheral surface, the knurling tool shaping part with the knurling tool shaped and the non-knurling tool shaping part without the knurling tool shaped are arranged on the peripheral surface and closely inserted into the pore such that the knurling tool shaping part and the non-knurling tool shaping part are present inside the pore. | 02-06-2014 |
20140077655 | STATOR AND ROTATING ELECTRICAL MACHINE - A stator includes: a stator core having an almost annular outer core and an inner core arranged inside the outer core; and a bobbin having a cylindrical body part around which a winding wire is wound and a flange part that is formed so as to rise up from the cylindrical body part, with a plurality of bent parts and an edge part. | 03-20-2014 |
20140084757 | ROTATING ELECTRICAL MACHINE - A motor includes: a almost annular stator, a rotor arranged inside the annular ring of the stator for rotating about a central axis, a sensor for detecting the rotation of the rotor, and a sensor board for implementing the sensor. The sensor and the sensor board are arranged outside the stator in the direction along the central axis. The sensor is a reflection type light projecting/receiving sensor. | 03-27-2014 |
20140125166 | ROTATING ELECTRICAL MACHINE - The disclosure discloses a rotating electrical machine including a stator and a rotor that are arranged facing each other via a magnetic air gap, an output shaft that is coupled to the rotor and is rotatably arranged by at least one bearing, and a fan that is coupled to the output shaft. The fan includes a disc portion configured to cover an end portion of the stator in an axial direction, and a plurality of blade portions that is provided on the stator side of the disc portion so as to protrude towards the stator. | 05-08-2014 |
20150137654 | ROTATING ELECTRIC MACHINE - This disclosure discloses a rotating electric machine including a tubular frame and a stator core. The frame includes a bulged linear part on an inner peripheral surface. The bulged linear part has a shape extended linearly in an axial direction and bulged toward the inner periphery side. The stator core is fixed onto an inner periphery of the frame. The stator core includes a groove part fitted to the bulged linear part on an outer peripheral surface. | 05-21-2015 |
20150288239 | BOBBIN AND ROTATING ELECTRICAL MACHINE - A bobbin is mountable to a stator iron core of a rotating electrical machine, and includes a body and a protrusion. Around the body, a coil wire is to be wound. The body has an opening side end. The protrusion protrudes from the opening side end of the body in a direction approximately parallel to a coil axial direction. A terminal of the coil wire is to be wound around the protrusion. | 10-08-2015 |
